It is still a new and different EOEnterpriseObject class. You may no be
adding data, but you are adding different behaviour.
Incidentally, if the new class is subset of the old class in terms of
attributes, why not make the old class a subclass of the restricted
class. Modeling your design effectively can make your life easy ....
not doing so can make your life hard.
By the way, if it is just display of, or access to, attributes you want
to hide, then this is a user/role/privileges problem whereby
conditionals in your WOComponents that depend on the session user, the
user's role and the user's privileges are used in the display of
certain fields.

Yeah, I'm just subclassing in code. I don't need to add any data,

Subject: Re: Subclass EO class to conditionally return values
Are you literally subclassing in code and not making a subclass in
the model? AFAIK, subclasses of EnterpriseObjects need to be defined
in the eomodel and the parent EO class needs to be defined there. If
that's what you have done, check your model.
See this:

I'd like to subclass one of my custom EO classes and change it to
only conditionally return some of its values. I figured I could
accomplish this by just overriding valueForKey. When I try to use
the subclass I get this error:
java.lang.IllegalStateException: Unabled to find an
EOClassDescription for objects of class RestrictedWeeklyInfo
How do I get around this? What's the best way to do something like
this?
Thanks,
John
